Title: Replacement element chip mounting method
Inventor: KURODA MASARU
IPC: H01L21/60
Filed: 1988-05-14
Abstract: PURPOSE:To make it possible to conduct a mounting operation in a precise manner by a method wherein a positioning mark is formed on the surface of a wafer, X-rays are permeated through the wafer, a bump is formed on the rear side of the wafer based on the positioning mark on the surface of the wafer, and a die-bonding work is conducted by a flip chip system using the bump on the rear side of the wafer. CONSTITUTION:A positioning mark 14 is formed on an arbitrary place based on the light-receiving element pattern on the surface of a wafer by conducting a photometrically method and anisotropic etching. Then, after a resist 16 has been formed on the rear side of the wafer 12, soft X-rays 18 pass through the wafer 12, the positioning mark 14 is detected by the intensity of the transmitted light of the X-rays 18, and a resist pattern is formed based on the position of said positioning mark 14. Also, a bump 22 is formed on the part which is exposed by the aperture of the resist 16 on the rear side of the wafer 12. After the wafer 12 has been cut into a chip, the chip 20 is bonded on the substrate 26 using a flip chip system. As a result, a highly precise mounting can be made possible.

Filed: 1983-07-01
Abstract: PURPOSE:To easily form a thin uniform layer on a conductive substrate having not only a flat plane but curved face by forming an electrostatic charge generating layer by the electrodeposition coating in a composite type electrophotographic sensitive material. CONSTITUTION:A composite type electrophotographic sensitive material is fabricated by a layer contg. a charge generating layer and a charge transfer layer on a conductive substrate, and this charge generating layer is formed by the electrodeposition coating to facilitate formation of a thin layer (about 1mum) not only on a plane plate but also on a curved conductive substrate like a drum face.

Title: Fuel injection nozzle for diesel engine
Inventor: SATOU YOSHIHIKO
IPC: F02B3/06
Filed: 1984-06-11
Abstract: PURPOSE:To assure the output under partial load area while to suppress Diesel knocking and to reduce the noise and vibration over the entire load area by providing a restrictor for enlarging the cross-section of main ejection hole in step from the low load area to the high load area in accordance with the lift of valve body. CONSTITUTION:In the throttle injection upto the lift L1, the cross-section of main injection hole 5 is restricted as conventional (clearance C2) to increase the fuel injection rate through sub-injection hole while in the throttle injection upto the lift L2, the cross-section of main injection hole 5 is enlarged (clearance C3) to increase the fuel injection through main injection hole 5. Upon exceeding of the lift L2, main injection is performed as conventional. Since proper fuel injection rate is set under partial load area to inject required amount of fuel during ignition delay interval, the noise can be reduced while maintaining the output. Since fuel is injected through sub-injection port under low load area, Diesel knocking is suppressed. Under high load area, it is similar with conventional one.

Title: Wick type kerosene burner
Inventor: HORIUCHI TOSHIHIRO
IPC: F23N5/24
Filed: 1984-06-08
Abstract: PURPOSE:To contrive to safely control the combustion by a structure wherein a relay, which turns ON and OFF by the change of current intensity on a flame rod, and a wick lifting mechanism to mechanically lower a wick by the action of a solenoid are equipped. CONSTITUTION:When the fuel in a burner rusn short during combustion, the combustion state turns to a state in fuel shortage and the concentration of carbon monoxide in exhaust gas starts to increase. However, on the other hand, the flame current also decreases followed by the disturbance of the state of flames and consequently the charging potential of a capacitor C2 becomes smaller than the predetermined value and the output of a comparing amplifier 15 inverts to LO. As a result, a transistor 17 is turned OFF and a relay 18 is deenergized, resulting in opening a relay contact 18a. In this case, if a switch 25 for cleaning is OFF, a solenoid 3 is deenergized and accordingly the shaft 3a of the solenoid 3 is pushed out by the force of a spring 3b so as to push down an iron sheet 4, resulting in disengaging the latch between the iron sheet 4 and a wick lifting gear 7 and falling the wick in order to stop the combustion.

Title: Recording current control system for data recording and reproducing device
Inventor: HASEGAWA OSAMU
IPC: G11B5/02
Filed: 1987-05-18
Abstract: PURPOSE:To prevent spike noise from entering a no-record section in a data recording and reproducing device using FM modulation, by causing FM carriers of low in level to be recorded for a fixed time at the time of stopping recording and reproducing of records. CONSTITUTION:Analog data signals 1 are FM-modulated by a voltage/frequency converter 3 and inputted to a variable frequency divider 4 which selects a frequency dividing ratio in accordance with a tape speed. The output of the frequency divider 4 is recorded on a magnetic tape 12 through a recording amplifier 5 and recording head 6. At the time of stopping and starting data signal recording, a recording mode signal control circuit 8 interrupts the input of an amplifier 2 for a fixed time so as to reduce the gain of the amplifier 5. Therefore, FM carriers which are lower in level as compared with the case of data signals are recorded on the magnetic tape for a fixed time. As a result, spike noise which is produced in a no-record section are completely prevented.

Abstract: PURPOSE: To improve response and precision by comparing the detection signal wave form of a hot-water supply temperature with a specified reference wave and changing the ON and OFF durations in a specified period of the reference wave thereby to control a gas valve.  
     CONSTITUTION: In a flash water boiler, the combustion heat of a main burner 5 is given to the water fed from a feed water pipe 2 in a heat exchanger 1, and the resulting hot water is supplied through a hot-water supply pipe 3. A temperature detector 15 detects the hot-water supply temperature on the downstream side of the heat exchanger 1 and generates an electrical output indicating the temperature change, and the output is changed by a converter 16 before fed to an electric-valve driving circuit 17. The conver 16 consists of a resistance-to-voltage converter 18, reference wave generator 19, control signal generator 20, and drive signal generator 21. When the hot-water supply temperature has fallen below a setpoint, the electric- valve ON duration in a predetermined period is prolonged to increase the gas amount, thereby raising the temperature. On the other hand, when the hot-water supply temperature has risen above the setpoint, the electric-valve OFF duration is prolonged to lower the temperature.
